Abstract
The invention discloses a light emitting diode (LED) powder spotting system. The system is characterized by comprising a host, an air pipe connected with the host, a spotting gun connected to the tail end of the air pipe and a precise electronic balance connected with the host. The host is used for detecting the weight of each drop of glue through the precise electronic balance and adjusting glue discharging time to ensure that actual discharging weight of the glue is consistent with a set value, so that the consistency of fluorescent powder during powder spotting operation each time is improved; therefore, the consistency of light colors of an LED module is ensured.
Description
Technical field
The present invention relates to a kind of LED manufacturing system and method, the particularly system and method for a kind of some powder operation.
Background technology
Existing high power white light LED (Light Emitting Diode; Light emitting diode) the main flow production method is on blue-light LED chip, to apply the silica gel that is mixed with yellow fluorescent powder; Blue light and gold-tinted are compounded to form white light; Therefore dot fluorescent powder is the processing step of a key, and the uniformity of fluorescent material is directly connected to consistency of colour.
Existing some powder system adopts pneumatic point gum machine mostly, the size through changing air pressure and the time of plastic emitting can regulate gel quantity how much.During dot fluorescent powder glue, compress into capable batch jobs through accurate setting-up time is gentle.
Very big shortcoming of this powder system; That can't follow the tracks of the phosphor gel viscosity change exactly; And glue viscosity is to change in the some glue process; This causes the actual gel quantity in the production process constantly to change, particularly when a some powder operation longer duration, when environment temperature is high the variation of glue viscosity more obvious.The gel quantity uniformity is bad will to cause the fluorescent material coating inhomogeneous, finally causes white light LEDs module colour consistency poor.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
To above-mentioned existing in prior technology problem and shortage, the purpose of this invention is to provide a kind of LED point powder system and LED point powder method that improves the led module colour consistency.
For realizing above-mentioned purpose, LED point powder system of the present invention can adopt following technical scheme:
A kind of LED point powder system is characterized in that: comprise main frame, the tracheae that links to each other with main frame, be connected in terminal some rifle of tracheae and the precise electronic balance that links to each other with main frame.
The present invention is compared with prior art: main frame detects the weight of every glue through the precise electronic balance; The main frame adjusting plastic emitting time makes the weight of actual plastic emitting glue; Improve the uniformity of fluorescent material in the each some powder operation, thereby guaranteed the photochromic uniformity of led module.
For realizing above-mentioned purpose, LED point powder method of the present invention can adopt following technical scheme:
A kind of LED point powder method of using LED point powder system; Led module is positioned on the precise electronic balance; Set the setting value of one every glue weight; Main frame is through the weight of every glue of precise electronic balance detection, if actual plastic emitting weight is different with setting value, the main frame adjusting plastic emitting time makes the weight of actual plastic emitting glue consistent with setting value.
The present invention is compared with prior art: the weight that detects every glue through main frame; If actual plastic emitting weight is different with setting value; The main frame adjusting plastic emitting time makes the weight of actual plastic emitting glue consistent with setting value; Improve the uniformity of fluorescent material in the each some powder operation, thereby guaranteed the photochromic uniformity of led module.
Description of drawings
Fig. 1 is the structural representation of LED point powder system of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment; Further illustrate the present invention; Should understand the following specific embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Please combine shown in Figure 1ly, the present invention discloses a kind of LED point powder system 100, the tracheae 20 that comprise main frame, links to each other with main frame, is connected in terminal some rifle 30 of tracheae 20 and the precise electronic balance 40 that links to each other with main frame.Said precise electronic balance 40 is treated the led module 101 of a powder in order to carrying.Use the LED point powder method of said LED point powder system 100 to be: led module 101 is positioned on the precise electronic balance 40; Set the setting value of one every glue weight; Main frame is through the weight of every glue of precise electronic balance 40 detections, if actual plastic emitting weight is different with setting value, the main frame adjusting plastic emitting time makes the weight of actual plastic emitting glue consistent with setting value; Thereby improved the uniformity of fluorescent material in the each some powder operation, thereby guaranteed the photochromic uniformity of led module.
Further; Before led module 101 is positioned over the precise electronic balance; Can increase the step of preparatory glue, through host setting air pressure and an initial time, begin to put in advance glue then earlier; Main frame reads the weight of preparatory glue and adjusts the plastic emitting time according to the difference of predetermined glue weight and setting weight from precise electronic balance 40; Conform to setting value until actual gel quantity, and then will treat that the led module 101 of a powder is placed on starting point powder operation on the precise electronic balance, thereby improve the accuracy rate of some powder.
